Possible Hybrid.. I need help buliding N/A

Well it looks like my B18c is toast. More info here:


If I go with a b18a or b20b/z should I use the b18c crank and rods?? Deck height is the same and the rod/stroke ratio of the b18c rotating assembly is better just slightly but it is better. I did a search and didn’t find anything. Does anyone know? I would like to rev this to 9k so every little bit helps…

Please help :confused:
